- adapted to be controlled or regulated so as l.lll

to cause the stream of water issuing from the hosel to 'be in the forni of a coarsebr iinespray, or 1n a solid stream, as may be desired..

lAn example oit such a hose nozzle is shown in 'the patent to Gibbs, No. 1,159,015.

The principal object of the present inven' tion is to provide a hose nozzle oi the "type referred to above,-in which the partfswhich cooperate to control the strearn which issues from the nozzle are accurately supported or maintained in the desired relative position while permitting a jnstrnent thereof, to vary thel kind ofstrearn. .n .Y

Another* object is to-'providea nozzle oit the class described in which means-.s provided :tor automatically shuttingbil the stream.; to provide a construction whichwill not be apt to develop lealrs to provide a structure. which is durable and convenient inuse g and in general, to provide an'improved nozzle oi the. `class described.

@ther objects and advantages of the invenvtion will beunderstoodby reference to thev following specification and accompanying drawingin which l have illustrated a nozzle and its mannery of connection and relationship to a hose with which it is used.

ln the drawing: Fig. lis a plan,"and Fig. 2 is a section on the line 2-2 of lig. l. Referring now to the drawings, l have in dicated a hose 5, which may be of any usual type of garden hose having av male coupling member 6 secured toits end. A. nozzle 7 is shown connected to the hose and includes a tubular or hollow body portion 8 having an odset intake portion '9 which is provided with an inlet passage 10 communicating with the interior of the hollow body portion 8 adjacent the outer end of the latter, as shown at ll. The oiiset intake portion-9 is provided 'with a female coupling portion l2 adapted to receive the coupling portion 6 of the hose, a suitable washer 13 being interposed between the' end of the hose and a portion of the nozzle for facilitating the boa: nut 16. Avalve stern 1'( is establishment of a watertight `ioint between the hose and nozzle.

A rlhe hollow body ortion 8 ont the nozzle is provided with a ischarge opening ltin its outer end and the rearward end of the nozzle is preferably counter-bored and threaded as shown atlsyto receive a stung inserted into the hollow body portion 8 through the open rear end thereof and the Ytorward end portion of the valve stern isprovided with altapered valve seat portion 18 which is adapted to engage a corner portion 19 around the discharge opening 14, which serves as a valve seat for receiving the'tapered portion lil ot the valve stern. lt will be apparent that `when the tapered seat 18 is seated on the valve seat 19, the discharge opening let ris closed so as to prevent the passage oli' water :trom the inlet 10 therethrough.

v 'lhe outer end of the valve stem is also provided with a head portion. 20,'which is adapted to cooperate with the discharge opening 14C to determine the lrind of stream which. will issue from the nozzle.- When the valve stein is moved rearwardly only a` slight amount, the head portion 20 is edective to cause the stream which issues from the nozzie to be in the form oi: a spray, and when the valve stem is moved rearwardly a con# siderable amount, or until the head 2O is en tirely within the body portion 8 ofthe nozzle,

a substantially solid stream will be discharged. Various :forms of streams will be discharged according to the relative position of the head portion 20 of the valve stem and the discharge or outlet opening le.

F or slidably supporting' and maintaining the valve stem substantially coaxial with the interior of the body portion 8,' and particular ly the forward end oi the'valve stem vcoaxial with the outlet 14,1 provide a bearing me1nber or part 2l in the body portion 8. rlhe bearing portion 2l is in the forni of an annular inwardly projecting erably formed integral with the body, and this bearing portion is preferably disposed as close to the outer end of the valve stein as conditions permit. As clearly shown in Fig. 2, the bearing 'member in the present Harige which is preilull instance is disposed in back of but immediately adjacent the inlet opening 11. The rear end of the valve stem v stream'issuing from the nozzle will always I be substantially the same for any one position 4vof adjustment of thehead 20 in or relative to the outlet. T he bearingy arrangement and firm support for the valve stem also insures proper seating of the valve seat 18 on the valve seat 1 9 to close the outlet.

The'stufng box nut 16 includes a recess 23 which is adapted to receive suitable packing-material 24 for preventing leakage around the rear end of the valve stem. For normally v maintaining the valve stem in its outward position of adjustment so that the valve seats 18 and 19 are in engagement and the discharge opening thereby closed, I provide the valve stem with an annular flange -25 which serves as a seat for receiving one 4end of a spring 26,

and which spring is compressed between the flange 25 and the charge of packing material 24, a washer 27 being :interposed between the end of the spring and thepacking material.

"It will be readily understood that the spring normally urges the valve stemoutwardly and at the same time tends to compress the packing material through the agency of the washer 27 to maintain the packing material tightly acked about thevalve stem. Hence, there is little likelihood of a leak developing around the rearward endl of the valve stem. i

Itwill also be notedftliat the bearing member 21 which is al fairly close fit around the valve stem 17 and the annular flange 25 which is preferably a fairly close-fit in the interior uol of the body member 8 tend to prevent the passage of water rearwardly in the body portion hso that there is butl little pressure davelopedl in the portion of the hollow bo y which is occupied by the spring 26, and hence the prevention of leakage around the rear end of the valve stem is facilitated.

v For controlling or actuating the valve stem 17 against the pressure of the spring 26, I provide a handle or lever 28 which is pivotally mounted at its' inner end on the coupling portion 12 of the intake, as shown at' 29. link 30 is pivotally connectedv to the rear end of the valve stem 17 as shown at 31 and to the lever 28 as shown at 82, so that the valve stem 17 may be pulled rearwardly against the pressure of the spring by depressing the lever 28.

withl the bodyV 8 byA -wardly the front end of the valve stem substantially Any suitable form of connection may be provided between the rear end of the valve stem described link connection is advantageous 1n that it avoids the placing of strains on the valve stem when the latter is pulled rearwardly, and in vthat it also prevents rotation of the valve stem within the `body 8, which might tend to prevent proper coactionfof the valve seats 18 and 19. As clearly shown in the drawings, the arrangement is such that thelever 28 extends over the adjacent end portion ofthe hose. This'constitutes a very desirable arrangement in that the hose serves as a counter part for the handle, that is to say, a fixed part towar easily be swung about its pivot, and also in that the hose part server: as a gripfor the nozzle whereby a very convenient and comfort- -able means for holding the same is provided. AThis arrangement also enables the nozzle to be very cheaply manufactured, since there is no excessive quantity of metal involved in its production. l

I Aam aware' thatchanges maybe made in the form, proportion and arrangement of parts without'departing from the spirit of the invention, the scope off which should be determined by reference vto the following claims, the latter being construed as broadly as possible, 'consistent with .the state of the art.
